Transformer Condition Health Monitoring and Predictive Maintenance of HVDC Converter Stations

The Technical Brochure (TB) reviews of current condition monitoring, diagnostic and prognostic methods and outlines recommendations to support the transition of HVDC substations toward predictive maintenance.

IT focuses on HVDC Voltage Source Converter (VSC) substations, particularly on VSC valves, i.e. power semiconductors, capacitors, valve-level power electronics and the cooling system.

Recommendations for advancing predictive maintenance in VSC-HVDC systems are given.
